## Methods

- [AddHelmChart(IResourceBuilder<KubernetesEnvironmentResource>, string, string, string)](/reference/api/csharp/aspire.hosting.kubernetes/kuberneteshelmchartextensions/methods.md#addhelmchart-iresourcebuilder-kubernetesenvironmentresource-string-string-string) : `IResourceBuilder<KubernetesHelmChartResource>` `extension` `ats export` -- Adds an external Helm chart to be installed in the Kubernetes environment. The chart is installed via `helm upgrade --install` as a pipeline step after the main application Helm chart is deployed.
- [WithDestroy(IResourceBuilder<KubernetesHelmChartResource>)](/reference/api/csharp/aspire.hosting.kubernetes/kuberneteshelmchartextensions/methods.md#withdestroy-iresourcebuilder-kuberneteshelmchartresource) : `IResourceBuilder<KubernetesHelmChartResource>` `extension` `ats export` -- Opts the Helm chart in to destroy-time uninstall. When set, `aspire destroy` will run `helm uninstall` for this release as part of the destroy pipeline.
- [WithForceConflicts(IResourceBuilder<KubernetesHelmChartResource>)](/reference/api/csharp/aspire.hosting.kubernetes/kuberneteshelmchartextensions/methods.md#withforceconflicts-iresourcebuilder-kuberneteshelmchartresource) : `IResourceBuilder<KubernetesHelmChartResource>` `extension` `ats export` -- Opts the Helm chart in to `helm upgrade --install --force-conflicts`. When set, Helm's server-side apply forcibly takes over any fields owned by another field manager instead of failing with a conflict.
- [WithHelmValue(IResourceBuilder<KubernetesHelmChartResource>, string, string)](/reference/api/csharp/aspire.hosting.kubernetes/kuberneteshelmchartextensions/methods.md#withhelmvalue-iresourcebuilder-kuberneteshelmchartresource-string-string) : `IResourceBuilder<KubernetesHelmChartResource>` `extension` `ats export` -- Sets a Helm value for the chart installation. Values are passed to `helm upgrade --install` via `--set` flags.
- [WithNamespace(IResourceBuilder<KubernetesHelmChartResource>, string)](/reference/api/csharp/aspire.hosting.kubernetes/kuberneteshelmchartextensions/methods.md#withnamespace-iresourcebuilder-kuberneteshelmchartresource-string) : `IResourceBuilder<KubernetesHelmChartResource>` `extension` `ats export` -- Sets the Kubernetes namespace for the Helm chart installation. If not set, the namespace defaults to the chart resource name.
- [WithReleaseName(IResourceBuilder<KubernetesHelmChartResource>, string)](/reference/api/csharp/aspire.hosting.kubernetes/kuberneteshelmchartextensions/methods.md#withreleasename-iresourcebuilder-kuberneteshelmchartresource-string) : `IResourceBuilder<KubernetesHelmChartResource>` `extension` `ats export` -- Sets the Helm release name for the chart installation. If not set, the release name defaults to the resource name.
